Hello!

I've a JTextArea in a JScrollPane... after some user's actions I
append some text in the JTextArea, but I'd like that it still shows
the first lines, while when I append text, the JScrollPane scrolls to
show the last added lines.
I tried with something like:

JScrollPane sp;

sp.getVerticalScrollBar().setValue(sp.getVerticalScrollBar().getMinimumValue());

but nothing happens... how can I solve?
Thanks!
